How many moles of each substance are needed to prepare the following solutions?
Afina-wow [57]
A) 7.5 % m / V 

7.5 g -------- 100 mL ( solution )
mass g ------ 45.0 mL

mass g = 45.0 x 7.5 / 100

mass g = 337.5 / 100 => 3.375 g

1 mole KCl -------------- 74.55 g
moles KCl ---------------- 3.375 g

moles KCl = 3.375 x 1 / 74.55 => 0.0452 moles of KCl
______________________________________________

b) 9.5 % ( m / V ) :

9.5 g -------- 100 mL ( solution )
mass g ------ 400.0 mL

mass g = 400.0 x 9.5 / 100

mass g = 3800 / 100 => 38 g

1 mole acetic acid -------------- 60.05 g
moles acetid acid  ---------------- 38 g

moles acetid acid = 38 x 1 / 60.05 => 0.6328 moles of  acetid acid<span>

What postulate of the kinetic molecular theory best explains why gases have high fluidity? because collisions between gas partic
slavikrds [6]

the elasticity of gas particle collisions, there is no energy loss when the particles pass one another. Gases are composed of a very large number of small particles, which spread out and avoid contact with one another.

<h3>Which of the following gas postulates from the kinetic molecular theory best explains why pressure exists in gases?</h3>

As the quantity of gas particles in the container rises, so does the frequency of wall interactions and subsequently the pressure of the gas. The average kinetic energy of a gas particle is exclusively dependent on the temperature of the gas, says the theory's final postulate. As the volume of gas particles inside the container grows, more of them will collide with the walls, increasing the pressure and the frequency of collisions.
